An active, intelligent botiid loach named for the dark 'Y-O-Y-O' markings young fish wear along the flank. Sociable and playful but needs a group, plenty of swimming room, and caves to feel secure.

Part of the Loaches
Bottom-dwelling, often social fish prized for sifting substrate, controlling pest snails, and adding constant motion to the lower levels of the aquarium. Most are scaleless or fine-scaled and sensitive to medications.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Long group tank
40 gal / 150 L (group of 5+)
Botia almorhae reaches 15 cm and is a social, active loach. Group of 5+ ESSENTIAL — solo fish are stressed and aggressive. Sand substrate, caves, 4-ft+ length.
Recommended
Long planted community
55–75 gal / 200–280 L
Group of 6–8 in a long planted tank with caves and driftwood. Pair with similarly active species. Eats snails — useful natural pest control.

Asian river biotope
90 gal+ / 340 L+ biotope
Long biotope with strong flow, abundant caves, and large group. Natural play behaviour, pile-sleeping, and audible clicking displays.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Fish eggs are small, translucent spheres, often laid in clutches on plants, substrate, or in a nest — or carried/brooded by a parent in livebearing and mouth-brooding species. A dark eye spot and the curled embryo become visible inside as development progresses.

Fry
Newly hatched fry are tiny and semi-transparent, frequently still carrying a yolk sac that fuels them before they feed freely. They lack full fin structure and adult coloration, staying near cover until they can swim and forage on their own.

Juvenile
Juveniles look like miniature adults but with developing fins and muted or different markings; many species shift pattern and color as they mature. Growth is rapid at this stage given clean water and steady feeding.
Adult
Adults show the species' full size, finnage, and mature coloration, and are sexually mature. Many fish develop sex-specific differences in size, color, or fin shape, which can intensify during breeding.
Habitat & enclosure
House a group in a tank of at least 40 gallons (150 L) with a 4 ft footprint; they are fast, restless swimmers. Target 75-86 F (24-30 C), pH 6.5-7.5, and soft to moderately hard water (3-12 dGH). Provide moderate, well-oxygenated flow and subdued lighting; dense planting and rockwork break up sightlines and reduce squabbling.
They originate from clear, flowing streams of the Ganges basin in the Himalayan foothills, so good circulation and pristine water suit them best.
Substrate
Use smooth sand or rounded fine gravel so they can sift and burrow without abrading their barbels and bellies. Aquascape with caves, driftwood tangles, and rock piles to provide hiding spots.
Equipment & setup
Run a strong canister or oversized hang-on-back filter for high oxygenation and turnover, plus a heater set to the mid-70s-low-80s F. A tight-fitting lid is essential, as loaches jump, and dim or floating-plant-shaded lighting keeps them out and active.
Diet
Omnivorous bottom forager. Feed sinking wafers and pellets supplemented with frozen bloodworms, brine shrimp, blanched vegetables, and the occasional snail, which they relish. Offer small amounts a few times daily so the whole group gets a share.
Behavior & temperament
Generally peaceful but boisterous and best kept in groups of 5 or more to spread out their pecking order and curb fin-nipping. They establish hierarchies with audible clicking sounds, do best with robust mid-water tankmates (barbs, larger tetras, danios), and should not be paired with slow long-finned fish. Avoid keeping with timid bottom dwellers that compete for the same space.
Health
Like all loaches they are scaleless-skinned and very sensitive to ich and to copper/medication overdoses; dose at half strength. Watch for skinny disease (internal protozoa/nematodes) causing wasting despite eating. Stable, clean, well-filtered water is the best preventive.
Tips, DIY & hacks
Acclimate slowly and keep them in an established, mature tank, as they are sensitive to new-tank instability. They are excellent natural snail controllers; add them to clear a pest-snail outbreak. Don't be alarmed by 'playing dead' on their sides, which is normal resting behavior.
